1. Algebra

   • Simplifying
     • EXAMPLES
       • t² x t³ = t⁵
       • y⁸ x y³ = y¹¹
       • p⁷÷ p⁵ = p²
       • m¹⁰÷m² = m⁸
   • Expand
   • Factorise
     • EXAMPLES
       • 8m²-12m = 4m(2m-3)
       • 12p²-8p = 4p(3p-2)
       • 6q²-9q = 3q(2q-3)
       • 16m²-12m = 4m(4m-3)
     • How Do You Factorise?
       • Step 1) You have to find the largest number that fits into the sequence or the most common letter.
         • e.g 12x-3a .The largest number that goes into both would be 3
         • e.g 12x²-3x . The most common letter would be x
       • Step 2) You then see how many time that letter or number can go into each side.
         • e.g 12x-3a. This would then be 3(4x-a)
         • e.g 12x²-3x . This would be x(12x-3)
   • Solve
   • nth Term
